CodeIgniter 控制器, 检测用户是否登录
<?php
/**
* 初始控制器
*/
class MY_Controller extends CI_Controller
{
// 是否检查用户登录状态
public $check_login = true; // 默认检查用户是否登录, 子类可以在 __construct() 中禁用它
public function __construct()

CodeIgniter重定向跳转提示函数, jump_error / jump_success 抠自ThinkPHP3.x
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
if (!function_exists('success'))
{
function jump_success($msg='操作成功', $url='javascript:history.go(-1);', $wait=2)
{
?>
